Description

La présente invention concerne un dispositif pour fixer une embase d'antenne sur une paroi métallique recouverte d'une couche protectrice iso­lante, ainsi qu'une rondelle dentée pour un tel dispo­sitif.The present invention relates to a device for fixing an antenna base to a metal wall covered with an insulating protective layer, as well as a toothed washer for such a device.

Lorsqu'on installe un poste autoradio ou un radio-téléphone, ou de façon plus générale un appareil de télécommunication, à bord d'un mobile tel qu'un véhicule automobile, il est nécessaire d'installer une antenne à l'extérieur du mobile et portée par ce der­nier. Dans le cas d'une automobile de tourisme, l'antenne est généralement disposée sur une aile, avant ou arrière, ou sur le toit. Pour ce faire, il est nécessaire de percer la tôle de la carrosserie afin de fixer l'embase de cette antenne, et de mettre à la masse la tresse du câble coaxial de liaison afin notamment d'éviter toute perturbation dans la réception ou l'émission des signaux radio-électriques.When installing a car radio or radio telephone, or more generally a telecommunication device, on board a mobile such as a motor vehicle, it is necessary to install an antenna outside the mobile and carried by it. In the case of a passenger car, the antenna is generally arranged on a wing, front or rear, or on the roof. To do this, it is necessary to pierce the sheet metal of the body in order to fix the base of this antenna, and to ground the braid of the coaxial connecting cable in order in particular to avoid any disturbance in the reception or the transmission of radio signals.

Cette mise à la masse est réalisée tout sim­plement en créant une continuité électrique entre la tôle de la carrosserie et la tresse grâce à une ron­delle dentée métallique, traversée par la tige de l'embase d'antenne et prenant appui sur la tôle. Mais, comme l'installation d'une telle antenne a lieu après peinture de la carrosserie, et même parfois après la vente du véhicule, la rondelle dentée pour être au contact de la tôle doit comporter des moyens permet­tant d'établir à coup sûr le contact de masse.This earthing is carried out quite simply by creating an electrical continuity between the body sheet and the braid by means of a metal toothed washer, crossed by the rod of the antenna base and bearing on the sheet. But, as the installation of such an antenna takes place after painting the bodywork, and even sometimes after the sale of the vehicle, the toothed washer in order to be in contact with the sheet metal must include means making it possible to establish without fail the ground contact.

Aussi un dispositif pour fixer une telle embase d'antenne comprend-il actuellement une rondelle métallique qui est munie de dents, traversée par la tige de l'embase d'antenne et qui doit être en contact avec la paroi métallique, et un organe de serrage pour appliquer cette rondelle dentée contre cette même paroi métallique. Mais, les dispositifs de l'art antérieur ont notamment pour inconvénient d'écraser les dents de la rondelle contre la paroi, de telle sorte que les dents ne percent pas, ou à tout le moins imparfaitment, la couche protectrice de peinture revêtant cette paroi métallique ou endommagent même cette paroi : dans ce dernier cas, il existe un risque important qu'apparaissent des points de corrosion dommageables à cet endroit.Also a device for fixing such an antenna base currently comprises a metal washer which is provided with teeth, traversed by the rod of the antenna base and which must be in contact with the metal wall, and a member tightening for apply this toothed washer against the same metal wall. However, the devices of the prior art have in particular the disadvantage of crushing the teeth of the washer against the wall, so that the teeth do not pierce, or at the very least imperfectly, the protective layer of paint coating this wall. metallic or even damage this wall: in the latter case, there is a significant risk of damaging corrosion points appearing there.

Aussi, un des buts de la présente invention est-il de fournir un dispositif pour fixer une embase d'antenne, reliée à un appareil de télécommunication, sur une paroi métallique, comprenant une rondelle dentée, de telle sorte que les dents percent la couche protectrice recouvrant la paroi afin de venir au con­tact de cette paroi sans la rayer de manière dommage­able ou sans s'écraser contre elle.Also, one of the objects of the present invention is to provide a device for fixing an antenna base, connected to a telecommunication device, on a metal wall, comprising a toothed washer, so that the teeth pierce the layer protective covering the wall in order to come into contact with this wall without scratching it in a damaging manner or without crashing against it.

Un autre but de l'invention est de fournir une rondelle dentée pour un tel dispositif.Another object of the invention is to provide a toothed washer for such a device.

Ces buts, ainsi que d'autres qui apparaîtront par la suite, sont atteints par un dispo­sitif pour fixer une embase d'antenne, notamment pour un appareil de télécommunication tel qu'un poste autoradio, sur une paroi métallique recouverte d'une couche protectrice isolante, cette embase d'antenne comprenant une tige propre à traverser un trou de la paroi, ledit dispositif comprenant une rondelle dentée métallique, traversée par cette tige et destinée à établir un contact de masse avec la paroi métallique, un organe de serrage étant prévu pour appliquer la rondelle dentée contre cette paroi en réponse à un effort de traction exercé sur la tige, par un moyen de fixation coopérant avec cette tige du côté de la paroi opposé à cette embase d'antenne, lequel dispositif est, selon la présente invention, caractérisé par le fait que chaque dent de la rondelle présente une pointe, dont l'inclinasion par rapport au plan moyen de la rondelle dentée est supérieure à l'inclinaison du reste de la dent, du côté d'application contre la paroi, et que des moyens d'appui sont prévus sur au moins l'un des deux éléments constitués par la ron­delle et l'organe de serrage, ces moyens d'appui ayant une épaisseur telle que lorsque le serrage de la ron­delle dentée est réalisé contre la paroi, un espace libre subsiste entre la paroi et la face en regard de l'organe de serrage afin de permettre une déformation élastique en flexion de la partie de la dent dont l'extrémité se termine par la susdite pointe, sans qu'il y ait blocage de cette partie entre l'organe de serrage et la paroi.These aims, as well as others which will appear subsequently, are achieved by a device for fixing an antenna base, in particular for a telecommunication device such as a radio set, on a metal wall covered with a protective layer. insulating, this antenna base comprising a rod suitable for passing through a hole in the wall, said device comprising a metal toothed washer, crossed by this rod and intended to establish ground contact with the metal wall, a clamping member being provided to apply the toothed washer against this wall in response to a tensile force exerted on the rod, by a fixing means cooperating with this rod on the side of the wall opposite to this antenna base, which device is, according to the present invention , characterized by fact that each tooth of the washer has a point, the inclination with respect to the mean plane of the toothed washer is greater than the inclination of the rest of the tooth, on the side of application against the wall, and that means d support are provided on at least one of the two elements constituted by the washer and the tightening member, these support means having a thickness such that when the toothed washer is tightened against the wall, a free space remains between the wall and the opposite face of the clamping member in order to allow an elastic deformation in bending of the part of the tooth whose end ends in the aforesaid point, without there being blockage of this part between the clamping member and the wall.

Avantageusement, la rondelle dentée et l'organe de serrage sont situés du côté de la paroi opposé à l'embase d'antenne, et les dents s'étendent radialement vers l'extérieur, la pointe de chaque dent constituant ainsi l'extrémité radiale extérieure de cette dent.Advantageously, the toothed washer and the clamping member are located on the side of the wall opposite to the antenna base, and the teeth extend radially outwards, the tip of each tooth thus constituting the radial end. outside of this tooth.

Les moyens d'appui ne débordent pas au-delà de la ligne passant par les racines des dents de telle sorte que les dents puissent fléchir sur toute leur longueur.The support means do not project beyond the line passing through the roots of the teeth so that the teeth can flex over their entire length.

De préférence, l'organe de serrage comprend une bague, en matière isolante, traversée par la tige et le moyen d'appui est constitué par une collerette, faisant saillie parallèlement à la direction axiale sur la face transversale de la bague tournée vers la rondelle, cette saillie étant prévue sur le bord périphérique interne de la bague et propre à prendre appui contre la rondelle proprement dite, les dents de la rondelle étant situées radialement à l'extérieur de la collerette au niveau d'un évidement annulaire ainsi défini par la collerette.Preferably, the clamping member comprises a ring, made of insulating material, traversed by the rod and the support means consists of a flange, projecting parallel to the axial direction on the transverse face of the ring facing the washer. , this projection being provided on the internal peripheral edge of the ring and adapted to bear against the washer proper, the teeth of the washer being located radially outside the flange at an annular recess thus defined by the collar.

Avantageusement, selon un autre mode de réalisation de la présente invention, les moyens d'appui sont constitués par des surépaisseurs prévues sur la rondelle dentée elle-même, dans une zone annu­laire située radialement à l'intérieur des dents. Les surépaisseurs sont situées entre la paroi et la ron­delle, c'est-à-dire du même côté de la dent que la pointe de cette dent. Ces surépaisseurs sont constituées par des languettes, solidaires de la ron­delle dentée et rabattues contre le plan de la ron­delle dentée ; ces languettes sont reliées au bord de l'ouverture de la rondelle et sont rabattues vers l'extérieur.Advantageously, according to another embodiment of the present invention, the support means consist of extra thickness provided on the toothed washer itself, in an annular zone located radially inside the teeth. The extra thicknesses are located between the wall and the washer, that is to say on the same side of the tooth as the tip of this tooth. These extra thicknesses are constituted by tongues, integral with the toothed washer and folded against the plane of the toothed washer; these tabs are connected to the edge of the opening of the washer and are folded outwards.

La surépaisseur, constituant le moyen d'appui, est, selon un autre exemple de réalisation, formée par au moins une zone emboutie de la région annulaire de la rondelle dentée. Cette zone emboutie peut former un anneau circulaire. Ces moyens d'appui peuvent également être constitués par plusieurs zones, en particulier quatre zones, embouties orientées radi­alement, prévues dans la partie annulaire de la ron­delle dentée et situées angulairement entre des dents.The additional thickness, constituting the support means, is, according to another exemplary embodiment, formed by at least one stamped zone of the annular region of the toothed washer. This stamped area can form a circular ring. These support means can also be constituted by several zones, in particular four zones, stamped oriented radially, provided in the annular part of the toothed washer and located angularly between teeth.

Avantageusement, chaque dent présente deux zones sensiblement planes, la première zone s'étendant entre la partie annulaire et la pointe, et ayant une première inclinaison par rapport au plan moyen de la rondelle, la deuxième zone constituant la pointe et ayant une inclinaison plus importante.Advantageously, each tooth has two substantially planar zones, the first zone extending between the annular part and the tip, and having a first inclination relative to the mean plane of the washer, the second zone constituting the point and having a greater inclination. .

Selon un autre mode de réalisation de la présente invention, chaque dent de la rondelle a une ligne moyenne courbe dont la concavité est destinée à être tournée du côté de la paroi.According to another embodiment of the present invention, each tooth of the washer has a curved mean line whose concavity is intended to be turned towards the side of the wall.

Ainsi qu'il a été dit précédemment, la présente invention est également relative à une ron­delle dentée pour un dispositif tel que décrit précédemment. Cette rondelle dentée, de préférence, comporte sur sa partie annulaire une surépaisseur obtenue en particulier par rabattement d'une languette, ou par un embouti.As mentioned above, the present invention also relates to a toothed washer for a device as described above. This toothed washer, preferably, has on its annular part an extra thickness obtained in particular by folding down a tongue, or by a stamped.

Ainsi qu'on peut le voir sur la figure 1, un dispositif pour fixer une embase 1 d'antenne, notam­ment pour un appareil de télécommunication tel qu'un poste autoradio, sur une paroi métallique 2 recouverte d'une couche protectrice isolante, comprend notamment une rondelle dentée 3 métallique et destinée à établir un contact de masse avec la paroi métallique 2. Ce dispositif comprend également un organe de serrage 4.As can be seen in FIG. 1, a device for fixing an antenna base 1, in particular for a telecommunication device such as a radio set, on a metal wall 2 covered with an insulating protective layer, comprises in particular a metal toothed washer 3 and intended to establish a ground contact with the metal wall 2. This device also comprises a clamping member 4.

L'embase 1 d'antenne est disposée de l'autre côté de la paroi métallique par rapport à la rondelle dentée métallique 3 et à l'organe de serrage 4. Cette embase d'antenne 1 comprend notamment une tige 5, qui traverse un trou ménagé dans la paroi 2 ; l'embase d'antenne, ainsi que son mode de fixation sur la paroi métallique, ne seront pas décrits plus avant puisqu'ils sont bien connus de l'homme du métier.The antenna base 1 is disposed on the other side of the metal wall relative to the metal toothed washer 3 and to the clamping member 4. This antenna base 1 in particular comprises a rod 5, which passes through a hole in the wall 2; the antenna base, as well as its method of attachment to the metal wall, will not be described further since they are well known to those skilled in the art.

L'organe de serrage 4 est prévu pour appli­quer la rondelle dentée 3 contre la paroi 2 en réponse à un effort de traction exercé sur la tige 5 par un moyen de fixation 6, constitué le plus souvent par un écrou coopérant avec cette tige 5, filetée, du côté de la paroi 2 opposé à l'embase d'antenne 1. En vissant l'écrou 6 sur la tige 5 on applique donc l'organe de serrage 4 contre la rondelle dentée métallique 3, de telle sorte que les dents 7, que comporte cette ron­delle 3 à sa périphérie, viennent au contact de la tôle métallique 2 après avoir percé la couche protec­trice isolante recouvrant cette paroi.The clamping member 4 is provided for applying the toothed washer 3 against the wall 2 in response to a tensile force exerted on the rod 5 by a fixing means 6, most often consisting of a nut cooperating with this rod 5, threaded, on the side of the wall 2 opposite the antenna base 1. By screwing the nut 6 on the rod 5, the clamping member 4 is therefore applied against the metal toothed washer 3, so that the teeth 7, which comprises this washer 3 at its periphery, come into contact with the metal sheet 2 after having pierced the insulating protective layer covering this wall.

Comme représenté sur les figures 4 et 5, chaque dent 7 de la rondelle 3 présente une pointe 8 dont l'inclinaison, par rapport au plan moyen de la rondelle, est supérieure à l'inclinaison du reste de la dent, du côté d'application contre la paroi 2. Selon l'invention, des moyens d'appui sont prévus sur la rondelle ou sur l'organe de serrage : ces moyens d'appui ont une épaisseur telle que lorsque le serrage de la rondelle 3 est réalisé contre la paroi 2, un espace libre subsiste entre la paroi 2 et la face en regard de l'organe de serrage 4, afin de permettre une déformation élastique en flexion de la partie de la dent 7 dont l'extrémité se termine par la pointe 8, sans qu'il y ait blocage de cette partie entre l'organe de serrage 4 et la paroi 2.As shown in Figures 4 and 5, each tooth 7 of the washer 3 has a tip 8 whose inclination, relative to the mean plane of the washer, is greater than the inclination of the rest of the tooth, on the side of application against the wall 2. According to the invention, support means are provided on the washer or on the clamping member: these support means have a thickness such that when the tightening of the washer 3 is carried out against the wall 2, a free space remains between the wall 2 and the opposite face of the clamping member 4, in order to allow an elastic deformation in bending of the part of the tooth 7 whose end ends in the tip 8, without there being blocking of this part between the clamping member 4 and the wall 2.

Selon un premier exemple de réalisation de la présente invention, représenté aux figures 1 et 2, les moyens d'appui sont constitués par une collerette 9 qui fait saillie parallèlement à la direction axi­ale, sur la face transversale de la bague 4, consti­tuant l'organe de serrage, tournée vers la rondelle dentée 3. Cette collerette 9 est située sur le bord périphérique interne de la bague 4 : elle prend donc appui contre la rondelle dentée 3 proprement dite, les dents 7 de la rondelle 3 étant situées radialement à l'extérieur de cette collerette. Cette collerette 9 ne déborde pas au-delà de la ligne (figure 4), constituée par un cercle, passant par les racines des dents 7. Un évidement annulaire 10̸ entre la paroi métallique 2 et la rondelle 3 se forme, lorsqu'on vient presser la bague 4 en direction de cette tôle 2. Une déformation élastique en flexion de la partie de la dent 7 est donc possible, pratiquement sur toute la longueur de la dent, sans qu'il y ait blocage de cette partie entre la bague 4 et la paroi 2. Ceci est d'autant mieux réalisé, que la largeur de la collerette 9 correspond à celle de la partie plane de la rondelle dentée 3.According to a first embodiment of the present invention, shown in Figures 1 and 2, the support means are constituted by a flange 9 which projects parallel to the axial direction, on the transverse face of the ring 4, constituting the clamping member, facing the toothed washer 3. This flange 9 is located on the internal peripheral edge of the ring 4: it therefore bears against the toothed washer 3 proper, the teeth 7 of the washer 3 being located radially to the outside of this collar. This flange 9 does not extend beyond the line (Figure 4), consisting of a circle, passing through the roots of the teeth 7. An annular recess 10̸ between the metal wall 2 and the washer 3 is formed, when one comes press the ring 4 in the direction of this sheet 2. An elastic deformation in bending of the part of the tooth 7 is therefore possible, practically over the entire length of the tooth, without there being blockage of this part between the ring 4 and the wall 2. This is all the better achieved when the width of the collar 9 corresponds to that of the flat part of the toothed washer 3.

Selon un autre mode de réalisation de la présente invention, les moyens d'appui sont constitués par des surépaisseurs prévues sur la rondelle dentée 3, dans une zone annulaire située radialement à l'intérieur des dents : cette zone annulaire est en fait la partie plane de l'exemple de réalisation précédent. Ces surépaisseurs peuvent être réalisées selon plusieurs modes, et sont situées entre la paroi et la rondelle, c'est-à-dire du même côté de la dent que la pointe de cette dent.According to another embodiment of the present invention, the support means consist of extra thicknesses provided on the toothed washer 3, in an annular zone located radially inside the teeth: this annular zone is in fact the planar part of the previous embodiment example. These extra thicknesses can be produced in several modes, and are located between the wall and the washer, that is to say on the same side of the tooth as the tip of this tooth.

Selon un premier mode décrit aux figures 6 et 7, les surépaisseurs sont constituées par des languettes 11 qui sont solidaires de la rondelle dentée 3 et rabattues contre la partie plane 12 de la rondelle dentée 3. Ces languettes 11 sont reliées au bord de l'ouverture de la rondelle dentée 3 et rabat­tues vers l'extérieur. Lorsque la rondelle dentée 3 est appliquée contre la tôle 2 par l'organe de ser­rage 4, comme représenté à la figure 7, il se forme un évidement 10̸ entre la dent 7 et la tôle 2 du fait de l'existence de la languette 11 qui s'interpose entre la partie plane 12 de la rondelle dentée 3 et la tôle 2.According to a first mode described in FIGS. 6 and 7, the extra thicknesses consist of tongues 11 which are integral with the toothed washer 3 and folded against the flat part 12 of the toothed washer 3. These tongues 11 are connected to the edge of the opening of the toothed washer 3 and folded outwards. When the toothed washer 3 is applied against the sheet 2 by the clamping member 4, as shown in FIG. 7, a recess 10̸ is formed between the tooth 7 and the sheet 2 due to the existence of the tongue 11 which is interposed between the flat part 12 of the toothed washer 3 and the sheet 2.

La dent 7 peut donc se déformer élastique­ment en flexion. sera décrit ultérieurement.Tooth 7 can therefore deform elastically in bending. will be described later.

Selon un deuxième mode de réalisation, représenté aux figures 8, 9 et 10̸, les moyens d'appui peuvent également être constitués par plusieurs , en particulier quatre, zones embouties 14 de la région annulaire 12 de la rondelle dentée 3. Ainsi, en ser­rant cette rondelle 3 contre la tôle 2, par l'organe de serrage 4, la zone annulaire 12 ne vient pas au contact de la tôle 2, ce qui crée ainsi un évidement 10̸ entre l'organe 4 et la paroi métallique 2.According to a second embodiment, shown in Figures 8, 9 and 10̸, the support means can also be constituted by several, in particular four, stamped areas 14 of the annular region 12 of the toothed washer 3. Thus, by tightening this washer 3 against the sheet 2, by the clamping member 4, the annular zone 12 does not come into contact with the sheet 2, which thus creates a recess 10̸ between the member 4 and the metal wall 2.

La zone emboutie peut être continue et par là même constituer une zone emboutie annulaire 15, comme représenté à la figure 10̸ ; cette zone annulaire emboutie 15 est située à la périphérie intérieure de la partie plane 12 de la rondelle dentée 3.The stamped area can be continuous and thereby constitute an annular stamped area 15, as shown in Figure 10̸; this stamped annular zone 15 is situated at the inner periphery of the flat part 12 of the toothed washer 3.

Ainsi qu'il a été dit précédemment, chaque dent 7 comporte une pointe 8 dont l'inclinaison, par rapport au plan moyen de la rondelle dentée 3, est supérieure à l'inclinaison du reste de la dent. En d'autres termes, chaque dent 7 présente deux zones sensiblement planes : la première 16 s'étend entre la partie annulaire 12 de la rondelle 3 et la pointe 8 de la dent, ainsi que l'on peut le voir sur la figure 4, et a une première inclinaison par rapport au plan moyen de la rondelle dentée 3 ; la deuxième zone con­stitue la pointe 8 elle-même, et a une inclinaison plus importante que la première. Pour fixer les idées, sans se limiter, la première inclinaison est de l'ordre de 30̸° à 45° à peu près, tandis que la seconde est, par exemple, de l'ordre de 5° à 10̸° par rapport à la première.As has been said previously, each tooth 7 has a tip 8 whose inclination, relative to the mean plane of the toothed washer 3, is greater than the inclination of the rest of the tooth. In other words, each tooth 7 has two substantially flat zones: the first 16 extends between the annular part 12 of the washer 3 and the tip 8 of the tooth, as can be seen in FIG. 4 , and has a first inclination relative to the mean plane of the toothed washer 3; the second zone constitutes the point 8 itself, and has a greater inclination than the first. To fix the ideas, without being limited, the first inclination is of the order of 30 ° to 45 ° approximately, while the second is, for example, of the order of 5 ° to 10 ° with respect to the first.

Bien évidemment, la dent 7 au lieu d'être formée par deux zones formant un angle entre elles, ainsi que par rapport à la partie annulaire 12 de la rondelle dentée 3, peut être de forme courbe, la ligne de courbure correspondant, sensiblement, à l'enveloppe d'une dent constituée par deux zones planes formant un angle entre elles. Ainsi, chaque dent a une ligne moyenne courbe dont la concavité est tournée du côté de la paroi métallique 2.Obviously, the tooth 7 instead of being formed by two zones forming an angle between them, as well as with respect to the annular part 12 of the toothed washer 3, can be of curved shape, the corresponding line of curvature, substantially, to the envelope of a tooth formed by two flat zones forming an angle between them. Thus, each tooth has a curved mean line whose concavity is turned towards the side of the metal wall 2.

Ainsi que peut le comprendre aisément l'homme du métier, une rondelle selon la présente invention, destinée à établir un contact de masse avec la paroi métallique 2, permet de réaliser, quel que soit le mode de réalisation de cette rondelle dentée, un ressort pour ce contact tout en perçant la couche protectrice de façon à venir en contact sur la tôle : on peut ainsi éviter les inconvénients présentés par les rondelles de l'art antérieur. Il y aura toujours contact par la pointe de la dent sur la zone griffée et dépourvue de couche isolante, grâce à cette double inclinaison combinée avec l'élasticité.As can be easily understood by those skilled in the art, a washer according to the present invention, intended to establish mass contact with the metal wall 2, makes it possible to produce, whatever the embodiment of this toothed washer, a spring for this contact while piercing the protective layer so as to come into contact on the sheet: one can thus avoid the drawbacks presented by the washers of the prior art. There will always be contact by the tip of the tooth on the scratched area and devoid of insulating layer, thanks to this double inclination combined with elasticity.
